GOST R 57166-2016

ГОСТ Р 57166-2016

Water. Determination of toxicity by survival rate of freshwater infusoria Paramecium caudatum Ehrenberg

Вода. Определение токсичности по выживаемости пресноводных инфузорий Paramecium caudatum Ehrenberg

Status: Effective - Introduced for the first time. IUS 5-2017

The standard applies to natural and drinking water, including bottled water, and establishes: - organoleptic methods for determining odor, taste and taste; - determination of turbidity using optical instruments. The determination of these water quality indicators is of great importance, since the presence of extraneous odor, taste, taste and high turbidity in water may indicate that the water is contaminated with foreign substances, poorly cleaned, and also repels the consumer, acting on his aesthetic feelings she is harmless

Стандарт распространяется на природные пресные воды (поверхностные и подземные), дехлорированные питьевые воды (централизованных систем и нецентрализованного питьевого водоснабжения), сточные воды (в том числе очищенные) с минерализацией не более 3 г/дм в степени 3, водные растворы веществ, буровые растворы, а также водные вытяжки донных отложений, твердых промышленных отходов, грунтов и почв, и устанавливает метод лабораторного биологического тестирования (далее-тестирования) для определения их токсичности с использованием пресноводных инфузорий Paramecium caudatum Ehrenberg (далее-тест-организмов) по выживаемости тест-организмов при тестировании в условиях переменного воздействия света и постоянной температуры. Настоящий метод позволяет определять токсичность исследуемых объектов и следующие токсикологические показатели (относительно контрольной пробы):-среднюю летальную кратность разбавления (ЛКР с индексом 50) пробы, вызывающую гибель 50 % тест-организмов, а также безвредную кратность разбавления пробы (ЛКР с индексом 10), вызывающую отклонение тест-параметра-выживаемости, за 6 или 96 ч не более 10 % относительно контрольной пробы;-среднюю летальную концентрацию (ЛК с индексом 50) растворов веществ, вызывающую гибель 50 % тест-организмов, и безвредную концентрацию (ЛК с индексом 10) растворов веществ, вызывающую отклонение тест-параметра-выживаемости, за 6 или 96 ч не более 10 % относительно контрольной пробы
